Early bladder dysfunction after vesicovaginal fistula repair: A prospective comparative analysis of transvaginal, open, and laparoscopic abdominal approaches.

We aim to compare the clinical and urodynamic profile oflower urinary tract symptoms (LUTS) in patients undergoing laparoscopic, open transabdominal, and laparoscopic transabdominal vesicovaginal fistulae (VVF) repair at 3 months of repair, that is, in early postoperative period. Fifty-one consecutive patients with endoscopically confirmed VVF were enrolled in our study over 2 years. Malignant fistulae, radiation-induced, and complex fistulae were excluded after cross-sectional imaging. All patients underwent a postoperative assessment for the success of the repair. Then at 3 months, they completed theAmerican Urological Association Symptom Score questionnaire and underwent a dual channel pressure-flow urodynamic study. The results of transvaginal, laparoscopic, and open transabdominal repairs were compared. All patients belonged to the Indian Caucasian race. The mean age was 35.43 ± 6.63 years. Thirty-two patients had supratrigonal and 19 had trigonal fistulae. Laparoscopic transabdominal repair was done in 15 patients, open transabdominal repair in 22 patients, and transvaginal repair in 14 patients. Forty-six patients reported some LUTS at a median follow-up of 5.83 ± 2.37 months postoperatively. Only 18 (35.2%) of these patients had moderate to severe symptoms The postoperative bladder dysfunction rates in open transabdominal, transvaginal and laparoscopic transabdominal groups were 36.4%, 28.6%, and 20%, respectively. Twenty-seven patients (52.9%) had some urodynamic abnormality, that is, small capacity (5), high voiding pressures (14), genuine stress incontinence (3), and poor compliance (3). Bladder capacity was a significant predictor of bladder dysfunction in our patients. In our study, all three surgical approaches were associated with bladder dysfunction, however, it was the least in the laparoscopic transabdominal approach. Postoperative bladder capacity is a significant predictor of bladder dysfunction.

HIV-associated rectovaginal fistulae in children: a single-centre retrospective study in the antiretroviral era

PurposeAcquired rectovaginal fistulae (RVF) are a complication of paediatric HIV infection. We report our experience with the surgical management of this condition.MethodsWe retrospectively reviewed the records of paediatric patients with HIV-associated RVF managed at Chris Hani Baragwanath Academic Hospital (2011–2023). Information about HIV management, surgical history, and long-term outcomes was collected.ResultsTen patients with HIV-associated RVF were identified. Median age of presentation was 2 years (IQR: 1–3 years). Nine patients (9/10) underwent diverting colostomy, while one demised before the stoma was fashioned. Fistula repair was performed a median of 17 months (IQR: 7.5–55 months) after colostomy. An ischiorectal fat pad was interposed in 5/9 patients. Four (4/9) patients had fistula recurrence, 2/9 patients developed anal stenosis, and 3/9 perineal sepsis. Stoma reversal was performed a median of 16 months (IQR: 3–25 months) after repair. Seven patients (7/9) have good outcomes without soiling, while 2/9 have long-term stomas. Failure to maintain viral suppression after repair was significantly associated with fistula recurrence and complications (φ = 0.8, p < 0.05).ConclusionWhile HIV-associated RVFs remain a challenging condition, successful surgical treatment is possible. Viral suppression is a necessary condition for good outcomes.

Correlates of fertility desires in women with urogenital fistula in the Democratic Republic of Congo: a cross-sectional study of 1,646 women

BackgroundStudies on fertility desires among fistula patients in the Democratic Republic of Congo (DRC) have been conducted on fewer patients. Furthermore, these studies have adopted a univariate descriptive approach. This study aims to examine the determinants of fertility desires among patients with fistula in the DRC.MethodsThis cross-sectional study included women aged 15–49 whose fistulas were repaired by the Panzi Hospital mobile team in seven DRC regions between 2013 and 2018. Univariate and bivariate descriptive analyses were performed using the frequency distribution table and the chi-square test. Adjusted odds ratios with their 95 confidence intervals from logistic regression were used to analyze factors associated with fertility desire after fistula repair. All analyses were stratified by parity level for all women aged 15–49 and 20–34 years.ResultsOf the 1,646 women aged 15–49 and 808 aged 20–34, 948 (57.6%) and 597 (73.8%), respectively, wanted to have children after fistula repair. Among women aged 15–49 and 20–34 years, the desire to have children was parity-specific. It was negatively associated with age at all parity levels. In women with low parity, the desire for children was significantly negatively associated with a high number of surgeries, abortions, and fistula duration. It tended to decrease with time, but was particularly high in 2014 and 2017. It was high among the Protestant women. Among medium-parity women, it was significantly lower in urban areas and among widows, but higher among women who had more than two abortions. Among high-parity women, it was negatively associated with education level.ConclusionTo help women with fistula achieve or approach their desired number of children, our findings suggest that (1) counseling is needed for women with a high desire for children; (2) the human, material, and financial resources needed to eliminate fistula in the DRC should be made available; and (3) medical and nursing staff should be sufficiently and effectively trained to minimize the number of unsuccessful surgeries performed on women with fistula.

Costs and outcomes associated with the administration of Intravenous Acetaminophen in neonates after esophageal atresia and tracheoesophageal fistula repair

BackgroundOver the last decade, the intravenous (IV) formulation of acetaminophen (APAP) has gained popularity as a safe and effective first-line analgesic in the neonatal intensive care unit and it is especially useful in peri-operative settings where oral agents are contraindicated. The primary objective was to examine the outcomes and costs associated with the use of IV APAP in combination with opioids versus opioids alone as a pain management strategy after neonatal esophageal atresia (EA) and tracheoesophageal fistula (TEF) repair. MethodsData from the Pediatric Health Information System was used to examine 1137 hospitalizations for EA/TEF repair from October 2015 to September 2018. Neonates administered opioids only, or IV APAP in combination with opioids as pain management, were included. ResultsNeonates receiving IV APAP experienced a longer median LOS, but a significantly lower mortality rate, a decreased mean daily cost, and reduced opioid use compared to neonates given only opioids. The two groups had no significant differences in pharmacy and total costs. ConclusionOur findings suggest that the use of IV APAP alongside opioids in EA/TEF repair is associated with reduced mortality and opioid use, as well as longer LOS.

Association of Operative Approach With Postoperative Outcomes in Neonates Undergoing Surgical Repair of Esophageal Atresia and Tracheoesophageal Fistula

IntroductionMinimally invasive surgery (MIS) is gaining traction as a first-line approach to repair congenital anomalies. This study aims to evaluate outcomes for neonates undergoing open versus MIS repairs for esophageal atresia/tracheoesophageal fistula (EA/TEF). MethodsIn this retrospective study, neonates undergoing EA/TEF repair from 2013 to 2020 were identified using the National Surgical Quality Improvement Program-Pediatric database. Proportions of operative approach (open vs. MIS) over time were analyzed. A propensity score-matched analysis using preoperative characteristics was performed and outcomes were compared including composite morbidity and reintervention rates (overall, major [thoracoscopy, thoracotomy], and minor [chest/feeding tube placement, endoscopy]) between operative approaches. Pearson's chi-square or Fisher's exact tests were used as appropriate. ResultsWe identified 1738 neonates who underwent EA/TEF repair. MIS utilization increased over time. Pre-match, neonates undergoing open repair were more likely to be premature, lower weight, ventilator dependent, and have cardiac risk factors with higher severity. Post-match, the groups were similar and included 340 neonates per group. MIS repair was associated with longer median operative time (209 vs. 174 min, p < 0.001) and increased overall post-operative intervention rates (7.6% vs. 2.9%, p = 0.01). There were no differences in composite morbidity (24.4% vs. 25.0%, p = 0.86) outside of reintervention. ConclusionMIS approach for neonates with EA/TEF appears to be associated with a higher rate of reinterventions. Further studies evaluating MIS approaches for the repair of EA/TEF are needed to better define short- and long-term outcomes. Type of StudyRetrospective comparative study.

Frequency of fistula in patients operated for primary cleft palate repair in a tertiary care center.

Objective: To determine the frequency of fistula in patients undergoing primary cleft palate repair. Study Design: Descriptive Case Series study. Setting: Burns and Plastic Surgery Center, HMC, Peshawar. Period: February 2023 to December 2023. Methods: Patient of both genders males and females undergoing primary cleft palate repair were included in the study with age ranging from 9 to 18 months age excluding patients with comorbids and syndromic patients. Non-probability consecutive sampling was adopted. The data was acquired from patients and hospital record and analyzed with statistical package for social sciences (SPSS). Results: Our study shows that among 169 patients, mean age was 10 months with SD ± 5.11. 100(59%) patients were male and 69(41%) patients were female. More over 3(2%) patients had fistula while 166(98%) patients didn’t had fistula. Conclusion: In this study we observed an internationally acceptable frequency of post-palatal repair fistula for primary cleft palate in our study population.

Thoracoscopic primary repair of esophageal atresia and tracheoesophageal fistula: Our early experience

Background: Thoracoscopic repair of esophageal atresia (EA) and tracheoesophageal fistula (TEF) has been practiced more frequently in the past two decades. This study focuses on assessing our early experience with implementing this minimally invasive technique in neonates. Methods: Neonates with EA/TEF who were admitted to the NICU at Ain Shams University hospitals during the period from 2021 to 2022 were enrolled in the study. Thoracoscopic primary repair was performed for neonates with a body weight exceeding 2 kg. Neonates with associated major cardiac, pulmonary, and neurological anomalies and long gap atresia were excluded from the study. Results: A total of 38 neonates presented with EA/TEF during the study period. Out of these neonates, 12 cases underwent thoracoscopic primary repair. The thoracoscopic approach was used to complete all necessary repairs, and no intraoperative complications occurred. The mean operating time was 125 minutes, ranging from 105 to 150 minutes. No evidence of leakage was found in any case, as determined by both clinical and radiological contrast swallow examinations. The mean ventilation time was 7.2 days, and the mean hospital stay was 21 days. There were four deaths attributed to complications related to barotrauma and sepsis. Conclusion: Thoracoscopic repair of EA can be performed safely, which yields favorable functional and cosmetic outcomes. However, it remains a challenging procedure that requires a long learning curve.

Development and Pilot Test of a Multi-Component Intervention to Support Women’s Recovery from Female Genital Fistula

Introduction and hypothesisWe evaluated a pilot multi-component reintegration intervention to improve women’s physical and psychosocial quality of life after genital fistula surgery.MethodsTwelve women undergoing fistula repair at Mulago Specialized Women and Neonatal Hospital (Kampala, Uganda) anticipated in a 2-week multi-component intervention including health education, psychosocial therapy, physiotherapy, and economic investment. We assessed feasibility through recruitment, retention, and adherence, acceptability through intervention satisfaction, and preliminary effectiveness through reintegration, mental health, physical health, and economic status. We collected quantitative data at enrollment, 6 weeks, 3 months, and 6 months. We conducted in-depth interviews with six participants. Quantitative data are presented descriptively, and qualitative data analyzed thematically.ResultsParticipants had a median age of 34.5 years (25.5–38.0), 50% were married/partnered, 42% were separated, 50$ had completed less than primary education, and 67% were unemployed. Mean number of sessions received was 12 for health education (range 5–15), 8 for counseling (range 8–9), and 6 for physiotherapy (range 4–8). Feasibility was demonstrated by study acceptance among all those eligible (100%); comfort with study measures, data collection frequency and approach; and procedural fidelity. Acceptability was high; all participants reported being very satisfied with the intervention and each of the components. Participant narratives echoed quantitative findings and contributed nuanced perspectives to understanding approach and content.ConclusionsOur results suggest that the intervention and associated research were both feasible and acceptable, and suggested certain modifications to the intervention protocol to reduce participant burden. Further research to determine the effectiveness of the intervention above and beyond surgery alone with regard to the health and well-being of women with fistulas is warranted.

Surgical repair of an aortoesophageal fistula after salvage thoracic endovascular aortic repair: a case report

BackgroundAn aortoesophageal fistula can prove to be fatal. Salvage thoracic endovascular aortic repair as a bridging therapy and radical surgery with thoracotomy should be considered while treating aortoesophageal fistula without spontaneous closure. Moreover, it is essential to select a technique that reduces the risk of reinfection. Here we report a rare case of a ruptured thoracic aortic aneurysm related to esophageal perforation by a fish bone that led to massive hematemesis and shock, and the surgical treatment of an aortoesophageal fistula that developed after salvage thoracic endovascular aortic repair.Case presentationA 70-year-old Japanese female patient was admitted with hematemesis, thoracic pain, and shock related to esophageal perforation of a ruptured descending aortic aneurysm caused by fish bone aspiration and esophageal perforation 1 month previously. An emergency thoracic endovascular aortic repair was performed. Postoperatively, an aortoesophageal fistula that remained open and a food intake-related increase in the inflammatory response was noted. Radical blood-vessel prosthesis implantation and fistula closure were performed. The patient’s postoperative course was favorable and the patient was discharged 22 days after the blood vessel prosthesis implantation.ConclusionSuch a case of rupture of a descending aortic aneurysm related to perforation by a fish bone and an aortoesophageal fistula is considerably rare. Thus, we report the therapeutic strategy of this particular case and review the relevant literature.

(110) THE SURGICAL ANATOMY OF CLITORAL INNERVATION: A REVIEW OF THE CURRENT MEDICAL LITERATURE

Abstract Introduction The clitoris is a crucial structure for sexual arousal and orgasm in people with gynecological anatomy. Despite its functional importance, the innervation of the clitoris has historically been understudied. The innervation of the clitoris includes somatic afferents of the dorsal nerve of the clitoris, a branch of the pudendal nerve and sacral plexus, and autonomic afferents of the cavernous nerve, a branch of the inferior hypogastric plexus. Although we have identified these structures, there remains a paucity of research on surgical techniques to avoid clitoral innervation during pelvic surgery, despite the importance of these nerves in gynecological sexual function. Objective This paper aims to summarize the current literature on clitoral innervation with special attention paid to the anatomical locations of nervous structures within the pelvis to inform future pelvic surgeons and reduce sexual side effects related to clitoral nerve damage. Methods We performed a PubMed search from inception through June 14, 2023 utilizing the Medical Subject Headings (MeSH) search terms “(clitor*)) AND (innerv* OR nerv*) AND (surg*)” and imported this search into Covidence software. Included in the literature search were observational studies, clinical trials, review articles, correspondence, and communications, and only articles in English were included. Results An initial abstract screen of 200 articles resulted in 87 articles that were fully screened and 53 articles that were utilized as within the scope of this paper. 45 papers discussed the dorsal nerve of the clitoris, while 15 papers explored autonomic afferents via the cavernous nerve. The anatomical location of the dorsal nerve of the clitoris has been tracked in 29 papers, most of which utilize cadaver dissection, with at least six anatomic variations identified. The cavernous nerve’s exact location, however, has not been traced as extensively as has the location of the dorsal nerve of the clitoris, perhaps due to its smaller diameter and shorter length. Additional innervation to the clitoris was proposed in 12 studies as well. Many studies suggested that commonly performed procedures, including midurethral sling placement for stress urinary incontinence, labiaplasty, clitoral hood reduction, clitoroplasty, and urogenital sinus repair may interfere with clitoral innervation if not otherwise modified. Two studies discussed sensory mapping techniques prior to pelvic surgery to account for anatomic variation in clitoral innervation. Conclusions The clitoris is a vastly innervated structure with both somatic and autonomic afferents whose locations and anatomic variations should be considered when performing pelvic surgery. Failure to consider not only the dorsal nerve of the clitoris but the cavernous nerve as well may have consequences that negatively impact clitoral sensitivity, engorgement and erection, orgasmic ability, and overall sexual function.

Human umbilical cord allograft associated with higher pediatric urethrocutaneous fistula repair success rates

Urethrocutaneous fistula (UCF) formation is a known complication following hypospadias repair, affecting between 5 and 70% of cases. Moreover, approximately 30% of patients experience refistulization after UCF repair. The use of extracellular matrices, such as AmnioCord, a dehydrated human umbilical cord allograft manufactured by MiMedx®, may mitigate high rates of refistulization. To determine whether the use of AmnioCord during UCF repair is associated with reduced incidence of subsequent UCFs among pediatric patients. Electronic medical records were retrospectively reviewed among 60 patients who underwent at least one UCF repair at a pediatric hospital in a large urban setting in the U.S. between January 2012-June 2018. Patients were followed through January 2024. Adjusted generalized estimating equation regression models were used to assess the association between AmnioCord use and rates of refistulization, while controlling for confounding variables. The number of fistula presentations per patient ranged from one to four; 53.3% had one fistula, 30.0% had two, and 16.6% had three or more. Overall fistula repair success rate was 56.8% but significantly differed by AmnioCord use in adjusted modelling; 69.4% of cases that received AmnioCord were successfully repaired, compared to 47.2% of cases that did not receive AmnioCord. In adjusted models, patients who received AmnioCord had 2.66 times greater odds of surgical success than patients who did not receive AmnioCord (95% CI:1.13-6.24; p=0.02). This study demonstrates a positive association between AmnioCord use and successful UCF closure among pediatric patients.

Internal mammary artery perforator flap for repair of an upper thoracic tracheo-oesophageal fistula

Tracheoesophageal fistulas (TOF) following esophagectomy for esophageal cancer are rare but potentially fatal. There is no consensus on treatment between stenting and surgical repair, although the latter is associated with better distant survival. In surgical repair, the interposition of a flap improves healing by providing well-vascularized tissue and reinforcing the repair zone. The flaps described are usually muscular and decaying. We present the case of a malnourished fifty-year-old man who underwent intrathoracic surgical repair of symptomatic recurrent TOF using a skin flap based on the perforators of the internal thoracic artery (IMAP). The perforator flap was completely de-epidermized and tunneled under the sternum by a proximal and limited resection of the 3rd costal cartilage and placed at the posterior aspect of the trachea, with the excess tissue rolled up on either side. At 9 months, the patient showed no recurrence and improved general condition. The de-epidermized IMAP tunneled under the sternum intrathoracically is a reliable alternative to the conventional muscle flaps described in TOF management and an attractive additional tool in the plastic surgeon's surgical arsenal.

Chronic schistosomiasis infection and obstetric fistula repair outcomes in Lubango, Angola: A retrospective chart review

AbstractObjectiveTo assess the association between chronic schistosomiasis infection, determined by bladder biopsies, and vesicovaginal (VVF) repair outcomes at an urban hospital in Angola. Other objectives were to quantify the prevalence of chronic schistosomiasis among patients with VVF and to assess agreement between pelvic X‐rays and bladder biopsies for chronic schistosomiasis diagnosis.MethodsIn this retrospective chart review, data were collected on patients who underwent VVF repair between 1 June 2022 and 30 November 2022 including: age, number of previous fistula repairs, Goh classification of fistula, X‐ray and biopsy results, fistula repair outcome, perioperative complications and postoperative incontinence. Age and number of previous repairs were described using means with standard deviations. Goh classification, X‐ray and biopsy results, fistula repair outcome, perioperative complications, and postoperative incontinence were described using frequencies. Parametric and nonparametric tests and Cohen's κ were calculated using R software and Excel.ResultsOf the 76 charts retrieved, 60 met inclusion criteria. The overall fistula repair failure rate was 26.7% (n = 16). There was no difference in the fistula repair failure rate between those with (26.9%) and without (26.5%) evidence of chronic schistosomiasis infection (χ2 = 2.33 e‐31, 95% confidence interval [CI]: −0.30, 0.28). The prevalence of chronic schistosomiasis was 43.3%. There was no agreement between X‐ray and biopsy in diagnosing chronic schistosomiasis infection (Cohen's κ = 0.23, 95% CI: −0.001, 0.47).ConclusionThere was no difference in the chance of fistula repair failure between those with evidence of chronic schistosomiasis infection and those without.

Transsphincteric Repair of Rectourethral Fistulas in Combination With Dartos Muscle Flap Interposition Following Radical Prostatectomy

OBJECTIVETo present our experience with a novel technique that combines the York–Mason transsphincteric approach with dartos muscle flap interposition to treat rectourethral fistulas. METHODSWe extracted records from our prospectively kept database of 35 procedures conducted for treating rectourethral fistulas during 2002–2023; the York–Mason approach was combined with dartos muscle flap interposition in five cases, performed for treating rectourethral fistulas due to radical prostatectomy, all of which were referral cases. RESULTSAll five patients were successfully treated and followed up for a median of 70.0 months without recurrence. Before the fistula repair, all had a diverting stoma. In all cases, the first voiding cystourethrogram revealed a healed fistula. The posterior and the scrotal incisions healed uneventfully. All patients reported normal voiding and no urinary incontinence. To date, the stoma has closed in three patients, all of whom had intact fecal continence and no postoperative anal stenosis. CONCLUSIONThe transsphincteric modified York–Mason approach combined with dartos muscle flap interposition resulted in complete healing of rectourethral fistulas.

Early approach for the iatrogenic vesico-vaginal fistula repair: a video case report.

Vesico-vaginal fistula (VVF) is a rare but debilitating condition, characterised by an abnormal connection between the bladder and vagina. While obstetric-related cases prevail in developing countries, iatrogenic fistulas are more common in industrialised ones, often resulting from pelvic surgeries. The optimal timing for surgical correction of VVF remains debated, often leaning towards delayed intervention. Here we report a successful early laparoscopic repair of an iatrogenic VVF following hysterectomy. The patient, a 54-year-old woman, presented with VVF after a hysterectomy. The laparoscopic repair was performed promptly upon diagnosis. To assess the feasibility and effectiveness of an early repair of a gynaecological-related VVF. First, cystoscopy identified the bladder edge of the VVF. Second, laparoscopy was performed and the vesico-vaginal dissection was carried out. The excision of the previous stitches and of the fibrotic tissue was undertaken to create free flaps for suturing. The bladder was repaired in a double layer, and a single layer was applied to the vagina. Finally, the omentoplasty was done. The patient was discharged on postoperative day 5. No complications occurred. This successful case demonstrates the feasibility and safety of early laparoscopic repair for gynaecological surgery-related vesico-vaginal fistulae. While acknowledging the need for further studies to standardise techniques, this report contributes to the evolving understanding of optimal management for this complex condition.

Perianal Fistulizing Crohn's Disease: Outcomes of Surgical Repairs and Current State of Stem Cell-Based Therapies

AbstractPerianal fistulizing Crohn's disease is one of the most disabling phenotypes of Crohn's disease, due to the severe impairment in quality of life including social and personal wellbeing. A multimodal approach with patient-tailored care is the key to optimal management of this condition. Medical therapy is needed to optimize the luminal disease, and surgical intervention is required to control any associated perianal sepsis and attempt palliative or definitive fistula repair. While several medical and surgical options are available, the majority of patients continue to have symptomatic disease. Fortunately, this continues to drive novel innovations which are revolutionizing the treatment and outcomes of perianal fistulizing Crohn's disease. However, there continues to be a need for randomized trials and consistent metrics utilized for classification and treatment outcomes in order to accurately describe optimal treatment outcomes.

Female non-obstetric urogenital fistula repair: long-term patient-reported outcomes and a scoping literature review.

To investigate long-term and patient-reported outcomes, including sexual function, in women undergoing urogenital fistula (UGF) repair, addressing the lack of such data in Western countries, where fistulas often result from iatrogenic causes. We conducted a retrospective analysis at a tertiary referral centre (2010-2023), classifying fistulas based on World Health Organisation criteria and evaluating surgical approaches, aetiology, and characteristics. Both objective (fistula closure, reintervention rates) and subjective outcomes (validated questionnaires) were assessed. A scoping review of patient-reported outcome measures in UGF repair was also performed. The study included 50 patients: 17 (34%) underwent transvaginal and 33 (66%) transabdominal surgery. History of hysterectomy was present in 36 patients (72%). The median (interquartile range [IQR]) operating time was 130 (88-148) min. Fistula closure was achieved in 94% of cases at a median (IQR) follow-up of 50 (16-91) months and reached 100% after three redo fistula repairs. Seven patients (14%) underwent reinterventions for stress urinary incontinence after transvaginal repair (autologous fascial slings). Patient-reported outcomes showed median (IQR) scores on the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS) of 5 (3-7) for filling symptoms, 1 (0-2) for voiding symptoms and 4.5 (1-9) for incontinence symptoms. The median (IQR) score on the ICIQ Female Sexual Matters Associated with Lower Urinary Tract Symptoms Module (ICIQ-FLUTSsex) was 3 (1-5). The median (IQR) ICIQ Satisfaction (ICIQ-S) outcome score and overall satisfaction with surgery item score was 22 (18.5-23.5) and 10 (8.5-10), respectively. Higher scores indicate higher symptom burden and treatment satisfaction, respectively. Our scoping review included 1784 women, revealing mixed aetiology and methodological and aetiological heterogeneity, thus complicating cross-study comparisons. Urogenital fistula repair at a specialised centre leads to excellent outcomes and high satisfaction. Patients with urethrovaginal fistulas are at increased risk of stress urinary incontinence, possibly due to the original trauma site of the fistula.

Proportions and determinants of successful surgical repair of obstetric fistula in low- and middle-income countries: A systematic review and meta-analysis.

Obstetric fistula is a serious and debilitating problem resulting from tissue necrosis on the reproductive and urinary and/or lower gastrointestinal tract organs due to prolonged labor. Primary studies of the treatment of obstetric fistulae report significantly variable treatment outcomes following surgical repair. However, no systematic review and meta-analysis has yet estimated the pooled proportion and identified the determinants of successful obstetric fistula surgical repair. To estimate the proportion and identify the determinants of successful surgical repair of obstetric fistulae in low- and middle-income countries. The protocol was developed and registered at the International Prospective Register of Systematic Reviews (ID CRD42022323630). Searches of PubMed, Embase, CINAHL, Scopus databases, and gray literature sources were performed. All the accessed studies were selected with Covidence, and the quality of the studies was examined. Finally, the data were extracted using Excel and analyzed with R software. This review included 79 studies out of 9337 following the screening process. The analysis reveals that 77.85% (95%CI: 75.14%; 80.56%) of surgical repairs in low and middle-income countries are successful. Women who attain primary education and above, are married, and have alive neonatal outcomes are more likely to have successful repair outcomes. In contrast, women with female genital mutilation, primiparity, a large fistula size, a fistula classification of II and above, urethral damage, vaginal scarring, a circumferential defect, multiple fistulae, prior repair and postoperative complications are less likely to have successful repair outcomes. The proportion of successful surgical repairs of obstetric fistula in low and middle-income countries remains suboptimal. Hence, stakeholders and policymakers must design and implement policies promoting women's education. In addition, fistula care providers need to reach and manage obstetric fistula cases early before complications, like vaginal fibrosis, occur.

Surgical repair of rectovaginal fistula by combined transanal and transvaginal endoscopy: a case report

The common causes of rectovaginal fistula include obstetric trauma, local infection, and rectal surgery, while rectovaginal fistula following hemorrhoid surgery is extremely rare. Rectovaginal fistulae (RVF) rarely heal without intervention. Surgical treatment is usually performed, but the optimal surgical method remains controversial. The patient was a 37-year-old woman who was transferred to our hospital due to an unsuccessful repair of a rectovaginal fistula after hemorrhoid surgery in a local hospital. The next day after admission, she had prophylactic ileostomy, fecal diversion and combined treatment with cephalosporin antibiotic to create a clean postoperative area. However, there was still fecal outflow from the vagina, with no significant reduction in excretion compared to previous surgery. Digestive endoscopy confirmed a failure of the repair for rectovaginal fistula. Therefore, preventive ileostomy was continued to reduce the accumulation of bacteria in the fistula and control the inflammation. After 8 weeks, the endoscopic fistula inflammation disappeared, and the condition of endoscopic surgery was considered to be mature. Subsequently, a new surgical method combining transanal endoscopy and transvaginal endoscopy was performed. After 12 weeks of surgery, a follow-up endoscopic examination showed that the fistula had been repaired and healed. During the 1-year follow-up, no serious complication was encountered, no recurrence was found, and the repair effect was satisfactory. In conclusion, a new technique combining transanal endoscopy and transvaginal endoscopy can effectively be used for the surgical repair of rectovaginal fistula after a hemorrhoid operation.
